The Collective continues their trek downwards towards the Underdark still on the mission to reclaim the piece of glass to restore the Mind of Ioun.  The party happens upon a crew of Duegar with a few dozen Drow slaves.  Doing the right thing, the Collective free the Drow by taking the lives of the slavers.  Continuing their journey down, after 5 more days of boring travel, the crew happens upon the first door they have seen in quite some time.  Yosmorn speaks the words on the door, and it unlocks.  What might lay before them?
